Earlier this month, Johns Hopkins researchers released a study through the Archives of Internal Medicine with the most conclusive evidence yet that low levels of vitamin D may have dire effects on one's health, greatly increasing the risk of premature death.

"Our results make it much more clear that all men and women concerned about their overall health should more closely monitor their blood levels of vitamin D, and make sure they have enough," says study co-lead investigator Erin Michos, M.D., M.H.S.
"We think we have additional evidence to consider adding vitamin D deficiency as a distinct and separate risk factor for death from cardiovascular disease, putting it alongside much better known and understood risk factors, such as age, gender, family history, smoking, high blood cholesterol levels, high blood pressure, lack of exercise, obesity and diabetes," says Michos.

Besides the already proven advantages of vitamin D supplementation for Osteoporosis and Cystic Fibrosis, it now appears that vitamin D may have even further reaching preventative benefits. Below are links back to the Archives of Internal Medicine abstract and a Science Daily write-up of the study:
